[0027] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 5 A shaping device 100 according to an embodiment of the present invention is described, comprising: a plurality of first pressing heads 10 and at least one second pressing head 11 .

[0028] Specifically, if Figure 1-Figure 5 As shown, a plurality of first pressing heads 10 are arranged at intervals along a first direction A, and a shaping space 12 is defined between two adjacent first pressing heads 10. The two adjacent first pressing heads 10 can move in the first direction A in directions approaching and moving away from each other; at least a portion of the second pressing head 11 is opposite to the shaping space 12, and the second pressing head 11 can move in a second direction B relative to the first pressing head 10, and the first direction A and the second direction B are perpendicular.

[0029] Combination Figure 1, the first pressing head 10 is arranged perpendicular to the first direction A, and a plurality of first pressing heads 10 are arranged at intervals along the first direction A to define a plurality of shaping spaces 12 distributed at intervals along the first direction A. The shaping device 100 is used to shape the appearance of the battery cell. The battery cell includes a pole core and a battery cell shell. The battery cell shell is arranged outside the pole core. The shaping device 100 is suitable for squeezing the battery cell shell so that the battery cell shell and the pole core are tightly attached to reduce the cavity between the pole core and the battery cell shell. The battery cell is arranged in the shaping space 12. When two adjacent first pressing heads 10 move in the direction of approaching each other in the first direction A, the two adjacent first pressing heads 10 respectively contact the two side surfaces of the battery cell along the first direction A, and squeeze the battery cell in the first direction A. The second pressing head 11 is arranged on one side of the shaping space 12 along the second direction B, that is, the side of the second pressing head 11 along the second direction B is opposite to the side of the battery cell along the second direction B. When the second pressing head 11 moves along the second direction B toward the direction close to the battery cell relative to the first pressing head 10, the second pressing head 11 contacts the side of the battery cell along the second direction B, and extrude one side edge of the battery cell in the second direction B, thereby assisting the shaping device 100 in the extrusion molding process of the battery cell in the second direction B.

[0030] According to the shaping device 100 of the embodiment of the utility model, the shaping device 100 is used to extrude and shape the shape of the battery cell so that there is multi-faceted contact and constraint between the pole core and the battery cell shell. The shaping space 12 is suitable for accommodating the battery cell and is the area where the battery cell is processed and formed. The two adjacent first pressing heads 10 can apply pressure to both sides of the battery cell in the first direction A, and can keep the battery cell in a horizontal position, eliminating the problem of uneven thickness of the battery cell after extrusion under the influence of gravity. The coordinated use of the second pressing head 11 and the first pressing head 10 can avoid stress concentration in the side arc area of ​​the battery cell during the extrusion process, thereby causing the internal fracture of the later expanded battery cell, reduce the risk of cracking in the arc area, and ensure product yield and safety in later use.

[0031] According to some embodiments of the present invention, Figure 2 As shown, when the second pressing head 11 moves relative to the first pressing head 10 toward the center of the first pressing head 10 , the second pressing head 11 is located in the shaping space 12 .

[0032] The second pressing head 11 is located in the shaping space 12. The second pressing head 11 that penetrates into the shaping space 12 can cooperate more closely with the work of the first pressing head 10, and apply balanced and directional pressure to the battery cell from multiple angles, which helps to eliminate stress concentration points that may be generated inside the material, reduce the risk of deformation or cracks, and thus improve the quality and consistency of the final product. The second pressing head 11 has a certain thickness in the first direction A. When two adjacent first pressing heads 10 approach each other along the first direction A, the second pressing head 11 can play a certain limiting role in the first direction A, preventing the two first pressing heads 10 from moving excessively, and avoiding excessive extrusion pressure on the battery cell, which may cause damage to the battery cell.

[0033] Therefore, the arrangement of the second pressure head 11 in the shaping space 12 helps to accurately control the size and shape of the battery cell, reduce the use of other limiting structures, simplify the overall structure of the shaping device 100, and ensure the high quality and performance stability of the product.

[0034] According to some embodiments of the present invention, Figure 2-4 As shown, at least a portion of the side surface of the second press head 11 facing the center of the first press head 10 is formed into a curved surface. The side surface of the second press head 11 facing the center of the first press head 10 is the side surface of the second press head 11 that contacts the battery cell along the second direction B. The side surface of the second press head 11 is a curved surface, so that when the second press head 11 contacts the battery cell, the pressure can be more evenly distributed on the surface of the battery cell, and the side surface of the pressed battery cell along the second direction B can be formed into a curved surface. Therefore, the design of at least a portion of the side surface of the second press head 11 being formed into a curved surface can reduce the local stress concentration phenomenon, ensure the processing quality, and the arc edge structure of the battery cell can also reduce the risk of cracking. The battery cell after extrusion can withstand a greater expansion force, and the safe use of the pole core can be ensured while further improving the energy density of the battery cell, thereby extending the service life of the battery cell.

[0035] Alternatively, the side surface of the second pressing head 11 facing the center of the first pressing head 10 is formed into a plane, that is, the side surface of the second pressing head 11 that contacts the side of the battery cell along the second direction B is formed into a plane, and the plane structure setting enables the second pressing head 11 to directly and clearly transmit the pressure vertically to the surface of the battery cell, which is convenient for controlling the size of the pressure and the moving distance of the second pressing head 11. Therefore, forming one side surface of the second pressing head 11 into a plane facilitates the manufacture of the second pressing head 11, simplifies the production cost of the second pressing head 11, and thus reduces the production cost of the shaping device 100.

[0036] According to some embodiments of the present invention, Figure 1-4 As shown, there are multiple second pressing heads 11, and the multiple second pressing heads 11 are respectively located on both sides of the first pressing head 10 along the second direction B, and the multiple second pressing heads 11 on both sides can move towards and away from each other. That is, each shaping space 12 is provided with a second pressing head 11 on both sides along the second direction B, and the two second pressing heads 11 are arranged opposite to each other along the second direction B. The battery cell is arranged in the shaping space 12 and is located between the two second pressing heads 11. The multiple shaping spaces 12 of the shaping device 100 correspond to the multiple second pressing heads 11 respectively.

[0037] Therefore, when the multiple second pressure heads 11 on both sides move in directions approaching each other, they can simultaneously apply pressure to both sides of the battery cell in the second direction B, so that the pressure received by the battery cell on both sides along the second direction B is the same, and the stress on the battery cell is evenly distributed, reducing the risk of uneven deformation and cracking during extrusion, which helps to maintain the structural integrity and performance stability of the battery cell.

[0038] According to some embodiments of the present invention, Figure 1 As shown, it further includes: at least one second pressing head 11 driving mechanism, the second pressing head 11 driving mechanism is connected to at least one of the plurality of second pressing heads 11 to drive the second pressing head 11 to move along the second direction B.

[0039] The second pressing head 11 driving mechanism can provide precise power output to ensure that the second pressing head 11 moves according to the preset trajectory and force. Each shaping space 12 corresponds to a group of second pressing heads 11, each group of second pressing heads 11 includes two second pressing heads 11, and the second pressing head 11 driving mechanism is connected to at least one of the second pressing heads 11 in each group.

[0040] Thus, the second ram 11 driving mechanism can control the movement of the second ram 11, so that the second ram 11 works in a predetermined mode, and the second ram 11 driving mechanism has a certain degree of adjustability, which can adapt to different processing requirements, so that the shaping device 100 can adapt to batteries of different materials or specifications. The power source of the second ram 11 driving mechanism can be electric (such as a servo motor), hydraulic or pneumatic system, etc., with a fast response speed and high control accuracy, so that the shaping device 100 can achieve the characteristics of efficient, accurate and repeatable processing, ensure high-quality molding of the battery cell, and improve processing efficiency.

[0041] According to some embodiments of the present invention, Figure 1-5 As shown, it further includes: a plurality of guide members 13, the plurality of guide members 13 all extend along the first direction A, the plurality of guide members 13 are spaced apart from each other in the second direction B, and the plurality of first pressing heads 10 are guided and matched with the plurality of guide members 13.

[0042] Multiple guide members 13 extend along the first direction A, providing a precise guide track for the first ram 10, and the first ram 10 moves along the first direction A relative to the guide member 13. Each first ram 10 is connected to the corresponding guide member 13 through a guide fit, ensuring the straightness and stability of the first ram 10 when moving along the first direction A, preventing deflection or shaking, and improving the accuracy of the shaping process. The multiple guide members 13 are arranged at intervals in the second direction B, which can enhance the structural rigidity of the entire shaping device 100 and improve the stability of the multiple first rams 10 when moving. The good guide fit between the guide member 13 and the multiple first rams 10 reduces the friction and wear of the first ram 10 during movement, and prolongs the service life of the first ram 10 and the entire shaping device 100.

[0043] Therefore, the housing in which the plurality of guide members 13 are arranged improves the movement accuracy of the shaping device 100 during movement and enhances the structural stability and reliability of the shaping device 100 .

[0044] According to some embodiments of the present invention, Figure 1-5 As shown, the plurality of guide members 13 are respectively located at the four corners of the plurality of first pressing heads 10 .

[0045] In some embodiments, there are four guide members 13, each of which is guided and matched with the plurality of first pressing heads 10, and the four guide members 13 are respectively arranged at the four corners of the plurality of first pressing heads 10. Mounting holes are formed at the four corners of the first pressing head 20, and the mounting holes are arranged through the first pressing head along the first direction A. The four guide members 13 are respectively arranged in the mounting holes of the first pressing head 20, and the four corners of each first pressing head 10 are provided with guide members 13, forming a stable frame structure, ensuring the verticality and parallelism of the pressing head during the up and down movement, and maintaining stable positioning even when a large pressure is applied, avoiding tilting or offset, and improving the processing accuracy.

[0046] Therefore, by arranging the guides 13 at the four corners, the force acting on the first pressure head 10 can be distributed more evenly, avoiding local stress concentration, thereby protecting the cell structure, ensuring uniform molding effect, and reducing the risk of deformation or damage. The design of the guides 13 positioned at the four corners simplifies the calibration process of the equipment, because the positioning of each pressure head only needs to adjust four points, which not only reduces the difficulty of debugging, but also facilitates daily maintenance inspections and necessary adjustments.

[0047] According to some embodiments of the present invention, Figure 1-5As shown, it further includes: two pressing plates 14, the two pressing plates 14 are respectively located on both sides of the multiple first pressing heads 10 along the first direction A, and the two pressing plates 14 can move in the first direction A in directions approaching and moving away from each other, so that the multiple first pressing heads 10 can move in the first direction A in directions approaching and moving away from each other.

[0048] The two pressing plates 14 are arranged in parallel with the plurality of first pressing heads 10, and the movement of the two pressing plates 14 toward and away from each other along the first direction A can drive the first pressing heads 10 to move in the same direction. The surfaces of the two pressing plates 14 on one side opposite to each other along the first direction A are respectively connected to the two first pressing heads 10 arranged at the outermost sides along the first direction.

[0049] Thus, the arrangement of two pressing plates 14 simplifies the driving mechanism, and the unified action of the pressing plates 14 realizes simultaneous and synchronous control of the multiple first pressing heads 10, ensuring that the pressure in the first direction A is applied evenly and synchronously, and improving the uniformity and efficiency of the shaping device 100 during movement. The large-area contact and driving mode of the pressing plates 14 can not only provide sufficient driving force to ensure that the stability of the system is maintained under high pressure, but also indirectly drive the multiple first pressing heads 10 through the two pressing plates 14 to reduce the number of driving components, simplify the overall structure of the shaping device 100, reduce the complexity of assembly and maintenance of the shaping device 100, and also reduce the production cost of the shaping device 100.

[0050] According to some embodiments of the present invention, Figure 1 As shown, it further includes: at least one first pressure head 10 driving mechanism, the first pressure head 10 driving mechanism is connected to at least one pressure plate 14, and the first pressure head 10 driving mechanism is used to drive the two pressure plates 14 to move in the first direction A in the direction of approaching and moving away from each other.

[0051] The driving mechanism of the first pressing head 10 is directly connected to at least one pressing plate 14. Through the operation of the driving mechanism of the first pressing head 10, the movement of the pressing plates 14 toward or away from each other in the first direction A can be automatically controlled, thereby driving multiple first pressing heads 10 to move synchronously.

[0052] Therefore, the setting of the driving mechanism of the first pressing head 10 improves the automation of the operation, reduces manual intervention, and improves production efficiency and safety. The linkage design of the driving mechanism and the pressing plate 14 ensures that the movement of all the first pressing heads 10 in the first direction A is highly synchronized, avoids the problem of uneven pressure caused by manual operation or mechanical mismatch, and ensures the dimensional accuracy and shape consistency of the battery cell during the forming process.

[0053] According to some embodiments of the present invention, Figure 1-5As shown, the driving mechanism of the first pressing head 10 includes: a plurality of lead screws 15 and at least one driver, the two ends of the plurality of lead screws 15 are respectively matched with two pressure plates 14, at least one of the two pressure plates 14 is movable along the axial direction of the lead screw 15 so that one of the two pressure plates 14 approaches and moves away from the other of the two pressure plates 14; the driver is connected to one end of at least one lead screw 15.

[0054] The lead screw 15 is a highly efficient transmission element, known for its good self-locking property and high transmission accuracy. An external thread is formed on the lead screw, and a connecting portion is formed on the pressure plate 14, which is suitable for cooperating with the pressure plate 14. An internal thread is formed on the inner wall of the connecting portion, and the pressure plate 14 and the lead screw 15 are matched by a threaded connection. When the driver rotates, the driving member can drive the lead screw 15 to spirally move relative to the pressure plate 14. Through the cooperation between the lead screw and the pressure plate 14, the spiral movement can be converted into a precise linear movement of the pressure plate 14 along the first direction A. The driver can be an electric motor, a hydraulic motor or a pneumatic motor, etc., which provides a power source and is directly connected to one end of the lead screw 15. By adjusting the speed and direction of the driver, the moving speed and direction of the pressure plate 14 can be conveniently controlled, thereby adjusting the pressing force and speed of the battery cell. There can be four lead screws 15, and the four lead screws 15 are respectively matched with the four corners of the two pressure plates 14.

[0055] Therefore, the application of the lead screw 15 can ensure that the pressure plate 14 and the connected first pressure head 10 are moved close to or away from each other with extremely high precision, thereby achieving accurate shaping of the battery cell. The design structure of the multiple lead screws 15 and at least one driver of the first pressure head 10 driving mechanism is relatively simple, durable, and has low maintenance costs. Regular lubrication and inspection can maintain its long-term stable operation, reducing downtime and maintenance costs, and ensuring the continuity and stability of production.

[0056] According to some embodiments of the present invention, as shown in the figure, it also includes: at least one heating element, which is arranged on at least one of the first pressure head 10 and the second pressure head 11.

[0057] The heating element can heat the battery core so that the battery core material softens after heating, reducing its hardness and brittleness, making it easier to shape. By precisely controlling the temperature and distribution of the heating element, it is possible to ensure uniform temperature throughout the entire molding area, avoid deformation or quality problems caused by local overheating or uneven cooling, and ensure the dimensional stability and consistency of the product. Therefore, integrating the heating element into the first pressure head 10 and / or the second pressure head 11 of the shaping device 100 not only significantly improves the molding efficiency and quality of the material, but also enhances the flexibility and adaptability of the shaping device 100, which can effectively improve production efficiency and product quality.
